If you enjoy playing Halo as much as Marathon then you should probably check out the Halathon topic in the projects section of this forum - it's currently being worked on again and a Demo release is only a few months away at most.

Also, if you have any suggestions or feature requests you can leave a comment and I will try to look into it if I find the time.

Varolac, hello. Hello, Vorlac. Welcome. To the Phformums. This is a good place for mapping and modding discussions, as well as miscellaneous things. If you're interested in the story of Marathon, specifically, then check out the Marathon Story Page. They tend to focus more on story discussions over there. http://forums.bungie.org/story/
